At present, decompressive craniectomy is an important surgical method for craniocerebral injury and cerebral hemorrhage, which can relieve the increase of intracranial pressure and brain swelling, and effectively save the lives of patients, so it is widely used clinically. After craniectomy and cranioplasty, the patient had a skull defect for a long time. Clinical studies have shown that decompressive craniectomy can easily lead to complications such as brain tissue swelling and subdural effusion due to skull defect. The postoperative neurological function of the patient deteriorates or the condition is exacerbated. At the same time, existing clinical studies have shown that postoperative bone window pressure bandage can effectively prevent encephalocele and brain swing, and prevent subdural effusion. At present, gauze bandages or elastic bandages are usually used clinically to bandage the bone window after decompressive craniectomy. reuse. Existing air bag pressurization bands also have certain limitations because they cannot carry out zone pressurization bandages on the brain.

There are various structures of the gas injection nozzle 7, and the present invention discloses the following two structures of the gas injection nozzle 7.
第一种：如图5、6、7所示，气嘴座10设有相连通的弹簧腔17和注气管导向孔18，弹簧腔17与气囊室16相通；注气管11插装在气嘴座10中，注气管11一端伸进气囊室16中，注气管11另一端与注气管导向孔18滑动配合，注气管11伸进气囊室16的一端安装有堵头13，注气管11侧壁设有通气孔15；弹簧腔17中安装有弹簧14，弹簧14套在注气管11上，在弹簧14的弹力下堵头13封住弹簧腔17与气囊室16的连通口12。堵头13的材质优选橡胶。进一步的，注气管11侧壁设有抵挡部19，弹簧14一端顶在弹簧腔17的内壁上，弹簧14另一端顶在抵挡部19上，在弹簧14的弹力下抵挡部19顶在弹簧腔17的内壁上。如图8所示，进一步的，通气孔15位于抵挡部19外侧。进一步的，连通口12的直径大于注气管11的外径。注气管11的内径与注射针筒出口管的外径适配，方便直接采用注射针筒注气，作为优选，注气管11的外端为锥形，注气管11位于抵挡部19外侧的一段的直径从内到外线性增加。注射针筒也方便控制注气量。The first type: as shown in Figures 5, 6, and 7, the air nozzle seat 10 is provided with a connected spring chamber 17 and an air injection pipe guide hole 18, and the spring chamber 17 communicates with the air bag chamber 16; the air injection pipe 11 is inserted into the air nozzle In the seat 10, one end of the gas injection pipe 11 extends into the air bag chamber 16, and the other end of the gas injection pipe 11 slides with the gas injection pipe guide hole 18, and the end of the gas injection pipe 11 extending into the air bag chamber 16 is equipped with a plug 13, and the side wall of the gas injection pipe 11 A vent hole 15 is provided; a spring 14 is installed in the spring chamber 17, and the spring 14 is sleeved on the gas injection pipe 11. Under the elastic force of the spring 14, the plug 13 seals the communication port 12 between the spring chamber 17 and the airbag chamber 16. The material of plug 13 is preferably rubber. Further, the side wall of the gas injection pipe 11 is provided with a resisting portion 19, one end of the spring 14 is pressed against the inner wall of the spring cavity 17, the other end of the spring 14 is pressed against the resisting portion 19, and under the elastic force of the spring 14, the resisting portion 19 is pressed against the spring cavity 17 on the inner wall. As shown in FIG. 8 , further, the vent hole 15 is located outside the resisting portion 19 . Further, the diameter of the communication port 12 is larger than the outer diameter of the gas injection tube 11 . The inner diameter of the gas injection pipe 11 is adapted to the outer diameter of the outlet pipe of the injection syringe, so that it is convenient to directly use the injection syringe for gas injection. As a preference, the outer end of the gas injection pipe 11 is tapered, and the gas injection pipe 11 is located at a section outside the blocking portion 19. The diameter increases linearly from inside to outside. The injection syringe is also convenient to control the amount of gas injection.
使用时用注射针筒向气囊注气，如图6所示，注射针筒的出气管插进注气管11并推动注气管11向内移动，使堵头13打开连通口12，此时推动注射针筒的活塞杆，注射针筒中的气依次通过通气孔15、弹簧腔17和连通口12流入气囊室16中。当气囊的充气量满足需求后，拔出注射针筒，如图5所示，弹簧14复位，在弹簧14推动抵挡部19向外移动，进而带动注气管11向外移动，堵头13又重新将弹簧腔17与气囊室16的连通口12密封住，实现气囊式16的密封。When in use, inject gas into the air bag with the injection syringe, as shown in Figure 6, insert the air outlet tube of the injection syringe into the gas injection tube 11 and push the gas injection tube 11 to move inward, so that the plug 13 opens the communication port 12, and at this time push the injection The piston rod of the syringe, the gas in the injection syringe flows into the air bag chamber 16 through the vent hole 15, the spring cavity 17 and the communication port 12 in sequence. When the inflation amount of the air bag meets the demand, pull out the injection syringe, as shown in Figure 5, the spring 14 resets, and the spring 14 pushes the resisting part 19 to move outward, and then drives the gas injection tube 11 to move outward, and the plug 13 is reset again. The communication port 12 between the spring cavity 17 and the air bag chamber 16 is sealed to realize the sealing of the air bag type 16 .
当需要放气或减小气囊压力时，把注射针筒的出气管插进注气管11并推动注气管11向内移动，使堵头13打开连通口12，此时抽动注射针筒的活塞杆，气囊室16中的气依次通过连通口12、弹簧腔17和通气孔15吸入注射针筒中。When it is necessary to deflate or reduce the pressure of the airbag, insert the outlet tube of the injection syringe into the gas injection tube 11 and push the gas injection tube 11 to move inward, so that the plug 13 opens the communication port 12, and at this time, pull the piston rod of the injection syringe , the air in the airbag chamber 16 is inhaled into the injection syringe through the communication port 12, the spring cavity 17 and the vent hole 15 in sequence.
第一种结构的注气嘴7与第一种的区别在于：如图9、10所示，通气孔15位于堵头13与抵挡部19之间。进一步的，通气孔15远离抵挡部19；作为优选，通气孔15位于注气管11与堵头13的连接。当通气孔15紧邻堵头13设置时，连通口12与注气管11间隙配合。使用时用注射针筒向气囊注气，如图9所示，注射针筒的出气管插进注气管11并推动注气管11向内移动，使堵头13打开连通口12，此时，注气管11上的通气孔15也伸进了气囊室16中；推动注射针筒的活塞杆，注射针筒中的气通过通气孔15直接流入气囊室16中。当气囊的充气量满足需求后，拔出注射针筒，如图5所示，弹簧14复位，在弹簧14推动抵挡部19向外移动，进而带动注气管11向外移动，堵头13又重新将弹簧腔17与气囊室16的连通口12密封住，实现气囊式16的密封。The difference between the gas injection nozzle 7 of the first structure and the first structure is that, as shown in FIGS. 9 and 10 , the vent hole 15 is located between the plug 13 and the resisting portion 19 . Further, the vent hole 15 is far away from the resisting portion 19 ; preferably, the vent hole 15 is located at the connection between the gas injection pipe 11 and the plug 13 . When the vent hole 15 is arranged adjacent to the plug 13 , the communication port 12 is in clearance fit with the gas injection pipe 11 . When in use, inject air into the air bag with the injection syringe, as shown in Figure 9, insert the air outlet pipe of the injection syringe into the air injection pipe 11 and push the air injection pipe 11 to move inward, so that the plug 13 opens the communication port 12, at this time, inject The vent hole 15 on the trachea 11 also extends into the air bag chamber 16; the piston rod of the injection syringe is pushed, and the gas in the injection syringe directly flows into the air bag chamber 16 through the vent hole 15. When the inflation amount of the air bag meets the demand, pull out the injection syringe, as shown in Figure 5, the spring 14 resets, and the spring 14 pushes the resisting part 19 to move outward, and then drives the gas injection tube 11 to move outward, and the plug 13 is reset again. The communication port 12 between the spring cavity 17 and the air bag chamber 16 is sealed to realize the sealing of the air bag type 16 .
本发明结构简单，佩戴方便，外科医生使用方便快捷，且可对颅脑进行分区加压，患者使用加压效果明显；气囊压迫使加压位置受力不均，且不易移位，又能重复利用，同时方便调节压力，尤其适用于去骨瓣减压术后的骨窗加压包扎。此外本发明采用插拔密封式的注气嘴，其与气囊连接为整体，不用担心遗失或者脱落，注气与密封都十分方便快捷。The invention is simple in structure, easy to wear, convenient and fast for surgeons to use, and can pressurize the brain in different regions, and the effect of pressurization is obvious for patients; It is easy to use and adjust the pressure at the same time, and it is especially suitable for the pressure bandage of the bone window after decompressive craniectomy. In addition, the present invention adopts a pluggable and sealed air injection nozzle, which is connected with the air bag as a whole, so there is no need to worry about losing or falling off, and the air injection and sealing are very convenient and quick.
当然，本发明还可有其它多种实施方式，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。Certainly, the present invention also can have other multiple implementation modes, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes All changes and modifications should belong to the scope of protection of the appended claims of the present invention.
